Hadronic vacuum polarization: comparing lattice QCD and data-driven results in systematically improvable ways
Michel Davier, Zoltan Fodor, Antoine Gerardin +7
The precision with which hadronic vacuum polarization (HVP) is obtained determines how accurately important observables, such as the muon anomalous magnetic moment, a_μ, or the low…
Cross-correlators of conserved charges in QCD
Rene Bellwied, Szabolcs Borsanyi, Zoltan Fodor +6
We present cross-correlators of QCD conserved charges at from lattice simulations and perform a Hadron Resonance Gas (HRG) model analysis to break down the hadronic contrib…
QCD and strongly coupled gauge theories: challenges and perspectives
N. Brambilla, S. Eidelman, P. Foka +46
We highlight the progress, current status, and open challenges of QCD-driven physics, in theory and in experiment. We discuss how the strong interaction is intimately connected to…
Strong Neutrino-Nucleon Interactions at Ultrahigh Energies as a Solution to the GZK Puzzle
Z. Fodor, S. D. Katz, A. Ringwald +1
After a short review of the ultrahigh energy cosmic ray puzzle - the apparent observation of cosmic rays originating from cosmological distances with energies above the expected Gr…
Relic neutrino masses and the highest energy cosmic rays
Z. Fodor, S. D. Katz, A. Ringwald
We consider the possibility that a large fraction of the ultrahigh energy cosmic rays are decay products of Z bosons which were produced in the scattering of ultrahigh energy cosmi…
Ultra high energy cosmic rays: clustering, GUT scale and neutrino masses
Z. Fodor
The clustering of ultra high energy (above 5\cdot 10^{19} eV) cosmic rays (UHECR) suggests that they might be emitted by compact sources. We present a statistical analysis on the s…

We present the results of our large scale 4-dimensional (4d) lattice simulations for the MSSM electroweak phase transition (EWPT). We carried out infinite volume and continuum limi…
Determination of absolute neutrino masses from Z-bursts
Z. Fodor, S. D. Katz, A. Ringwald
Ultrahigh energy neutrinos (UHEν) scatter on relic neutrinos (Rν) producing Z bosons, which can decay hadronically producing protons (Z-burst). We compare the predicted proton spec…

Z. Fodor, S. D. Katz
The spectrum of ultrahigh energy (above \approx 10^{9} GeV) cosmic rays is consistent with the decay of GUT scale particles. The predicted mass is m_X=10^b GeV, where b=14.6_{-1.7}…
Ultra High Energy Cosmic Rays from Compact Sources
Z. Fodor, S. D. Katz
The clustering of ultra high energy (above 10^20 eV) cosmic rays (UHECR) suggests that they might be emitted by compact sources. Statistical analysis of Dubovsky et al. (Phys. Rev.…
Electroweak Phase Transition in the MSSM: 4-Dimensional Lattice Simulations

Recent lattice results have shown that there is no Standard Model (SM) electroweak phase transition (EWPT) for Higgs boson masses above \approx 72 GeV, which is below the present e…
